What is the xintercept for 5x - 4y equals 18?
To find the x-intercept for 5x - 4y = 18, plug in a 0 for the y value and solve for x. 5x - 4(0) = 18 5x = 18 x = 18/5 or 3.6 The line will hit the x-axis at (3.6,0)
Write the equation of the line passing through the points 0 -4 and -2 2?
slope = 2-(-4)/-2-0 = 2+4/-2 = 6/-2 = - 3 So y=-3x+b Substitute the coordinate (0,-4) -4=-3(0)+b, -4=0+b, -4=b, y intercept is -4 Substitute that for b y=-3x-4 So the answer is y=-3x-4
Which ordered pair is a solution to the equation y - 2x 6?
For example, if you have (0, 6) or (3, 1). Which of them is a solution to y - 2x = 6? Check (0, 6): y - 2x = 6, substitute 0 for x, and 6 for y into the equation 6 - 2(0) =? 6 6 - 0 =? 6 6 = 6 True, then (0, 6) is a solution. Check (3, 1): y - 2x = 6, substitute 3 for x, and 1 for y into the equation 1 - 2(3) =? 6 1 - 6 =? 6 -5 = 6 False, then (3, 1) is not a solution.
How do you find the y-intercept of a function?
The y-intercept is the value of a function f when x is equal to zero. So, substitute 0 for x into the equation and find the value of y.
The line whose equation is y equals 4x plus 2 has a y-intercept whose coordinates are?
When finding the y-intercept, plug in x=0 y = 4x + 2 y = 4(0) + 2 y = 2 So your intercept is (0,2)
Find the xintercept for the equation y equals 8x squred?

In finding the y-intercept of y equals x-4 what do you do to work the equation?
Substitute the value x = 0 in the equation of the line. Here you get y = 0-4 = -4. So, the y-intercept is -4 ie the line intercepts the -axis at (0,-4).
How do you determine x and y in the same mathematical problem?
substitute 0 for y and solve for x. then substitute x for 0 and solve for why and you have the x and y coordinates
How do you calulate intercept?
x-intercept: 1. substitute 0 for y 2. solve for x y-intercept: 1. substitute 0 for x 2. solve for y
How do you calculate the y-intercept?
Substitute x = 0.
What are the x- and y-intercepts of the line with equation 4x plus 5y equals 40?
First, put the equation in slope-intervcept form y=mx + b 5y=4x + 40 The y intercept is where x=0 so- 5y= 4(0) +40 solve for y y intercept = (0,8) For the x intercept, y=0 0=4x+40 -4x=40 x= -10 xintercept =( -10.0)
How do you find the y-intercept of y equals 2x?
Y intercept occurs where x=0. Substitute x=0 in this equation. Y = 2(0) Y = 0 For the x-intercept, substitute y=0: 2X = 0 X = 0 This is a line that passes through the origin. If the graph looks like y = ax + b, the y-intercept is at the point b (b can be positive or negative), and the x intercept is (-b/a).
Why do we substitute zero for the value of y when finding the solutions of quadratic equations?
Because the solutions are found on the x axis when y is zero.
What is the xintercept of y2x 5?
As written this is not a graphable thing. I does not represent a graphable equation because there is no "=" sign. Whatever the equation might be, the x intercept is found by setting y=0, which leaves you with an equation for x, which is the intercept.
How do you graph an equation in slope intercept form?
Slope intercept is y=mx+b Now, substitute 0 for x, and y=b. Plot the point (0,y) Then, substitute 0 for y, this one is a bit more complex: 0=mx+b -b = mx -b/m = x Since you have those values for b and m, substitute them in and you will have your value for x. Plot the point (x,0). Now for the fun part.... CONNECT THE DOTS! And you're done, you've plotted the equation. You can also substitute other values for x and y, but I personally find 0 to be the easiest.
How do find the y intercept?
Substitute x=0 into a y=mx+b formula (with b filled in) and solve for y
Find intercept of y -25x plus y equals 65?
-25x+y=65-25(0)+y=65y=65When finding a y-intercept you replace the value of xwith 0. The same goes for finding the x-intercept, you replace the value of y with 0 and simplify the equation.
